BAI1-associated protein 3 is a protein that in humans is encoded by the BAIAP3 gene.[3][4]

This p53-target gene encodes a brain-specific angiogenesis inhibitor. The protein is a seven-span transmembrane protein and a member of the secretin receptor family. It interacts with the cytoplasmic region of brain-specific angiogenesis inhibitor 1. This protein also contains two C2 domains, which are often found in proteins involved in signal transduction or membrane trafficking. Its expression pattern and similarity to other proteins suggest that it may be involved in synaptic functions.[4]


BAIAP3 has been shown to interact with Brain-specific angiogenesis inhibitor 1.[3]
